在动物社会中，化学通讯在冲突与合作中发挥着重要作用。对于蚂蚁来说，非巢蚁产生的表皮碳氢化合物（CHC）混合物会引起明显的攻击性。我们描述了木蚁 Camponotus japonicus 触角上的感觉感受器，其功能是辨别同巢伴侣。该感器是多孔的，仅对非同巢 CHC 混合物有反应。这表明外周识别机制在检测集落特异性化学信号中的作用。
In animal societies, chemical communication plays an important role in conflict and cooperation. For ants, cuticular hydrocarbon (CHC) blends produced by non-nestmates elicit overt aggression. We describe a sensory sensillum on the antennae of the carpenter ant Camponotus japonicus that functions in nestmate discrimination. This sensillum is multiporous and responds only to non-nestmate CHC blends. This suggests a role for a peripheral recognition mechanism in detecting colony-specific chemical signals.
